SKU CH-TH6X-CN8G8

16 GB DDR4 desktop memory module running at 2666 MHz with CL19 latency and 1.2 V operation

  • Capacity16GB
  • 16 GB capacity for heavy multitasking

16GB DDR4 DIMM for desktop upgrades

This 16GB DDR4 module uses a 288-pin DIMM form factor and runs at 2666MHz with a CL19 latency. It operates at the standard 1.2V and is unbuffered non-ECC memory. The stick adds a single 16GB rank to a desktop system that has a free DDR4 slot.

DDR4 2666MHz practical limits

The DDR4 2666MHz interface caps transfer rates at PC4-21300 bandwidth. Motherboards that only support lower DDR4 speeds will downclock this module automatically. Systems already running faster DDR4 will not gain extra throughput from this stick alone.

Replaces smaller or slower DDR4 modules

Swapping an 8GB or lower-capacity DDR4 DIMM for this 16GB unit doubles the memory available to the operating system. The upgrade is worthwhile when the current kit limits multitasking or when an empty slot allows a simple capacity increase without replacing matched pairs.

Questions about this item

Should I choose the 16 GB module or add a second stick for dual-channel?

A single 16 GB DIMM runs in single-channel mode; adding an identical stick enables dual-channel bandwidth on most desktop platforms.

What does the 2666 MHz rating deliver once the module is installed?

The module operates at 2666 MHz with CL19 latency at 1.2 V, giving a peak transfer rate of PC4-21300 on compatible motherboards.

How does the DDR4 288-pin interface limit performance in practice?

The 288-pin DDR4 interface caps the module at 2666 MHz and 1.2 V; faster speeds require a motherboard and CPU that support higher DDR4 data rates.
